Abstract

Objective: To examine which factors are driving improvement in the Dialysis Facility Compare (DFC) star ratings and to test whether nonclinical facility characteristics are associated with observed longitudinal changes in the star ratings. Data Sources: Data were collected from eligible patients in over 6,000 Medicare-certified dialysis facilities from three annual star rating and individual measure updates, publicly released on DFC in October 2015, October 2016, and April 2018. Study Design: Changes in the star rating and individual quality measures were investigated across three public data releases. Year-to-year changes in the star ratings were linked to facility characteristics, adjusting for baseline differences in quality measure performance. Data Collection: Data from publicly reported quality measures, including standardized mortality, hospitalization, and transfusion ratios, dialysis adequacy, type of vascular access for dialysis, and management of mineral and bone disease, were extracted from annual DFC data releases. Principal Findings: The proportion of four- and five-star facilities increased from 30.0% to 53.4% between October 2015 and April 2018. Quality improvement was driven by the domain of care containing the dialysis adequacy and hypercalcemia measures. Additionally, independently owned facilities and facilities belonging to smaller dialysis organizations had significantly lower odds of year-to-year improvement than facilities belonging to either of the two large dialysis organizations (Odds Ratio [OR]: 0.736,95% Confidence Interval [CI]: 0.631-0.856 and OR: 0.797, 95% CI: 0.723-0.879, respectively). Conclusions: The percentage of four- and five-star facilities has increased markedly over a three-year time period. These changes were driven by improvement in the specific quality measures that may be most directly under the control of the dialysis facility. KEYWORDS public reporting, quality measures, star ratings, dialysis, medicare, 1 | INTRODUCTION In 2000, Dialysis Facility Compare (DFC) emerged as one of the earliest public reporting programs implemented by the Centers for Medicare & Medicaid Services (CMS) and has [...]

Abstract

Objective. To analyze variation in medical care use attributable to Medicare's decentralized claims adjudication process as exemplified in home hemodialysis (HHD) therapy. Data Sources/Study Setting. Secondary data analysis using 2009-2012 paid Medicare claims for HHD and in-center hemodialysis (IHD). Study Design. We compared variation across Medicare administrative contractors (MACs) in predicted paid treatments per standardized patient-month for HHD and IHD patients. We used ordinary least-squares regression to determine whether higher paid HHD treatment counts expanded HHD programs' presence among dialysis facilities. Data Collection. We identified HHD and IHD treatments using procedure, revenue center, and claim condition codes on type 72x claims. Principal Findings. MACs varied persistently in predicted HHD treatments per patient-month, ranging from 14.3 to 21.9 treatments versus 10.9 to 12.4 IHD treatments. The presence of facilities' HHD programs was uncorrelated with average HHD payment counts. Conclusions. Medicare's claims adjudication process promotes variation in medical care use, as we observe among HHD patients. MACs' discretionary decision making, while potentially facilitating innovation, may admit inefficiency in care practice as well as inequitable access to health care services. Regulators should weigh the benefits of flexibility in local coverage decisions against those of national standards for medical necessity. Key Words. Variation, Medicare, dialysis, It is a basic assumption of much of the geographic variation literature that Medicare beneficiaries have coverage for the same set of services if they receive care in Alaska or [...]

50. Case Management: Effects of Improved Risk and Value Information

Author

Weissert, William G., Hirth, Richard A., Chernew, Michael E., Diwan, Sadhna, and Kim, Jinkyung

Abstract

Purpose: The purpose of this study was to determine the impact on resource use of providing case managers with information on the potential for patients to benefit from home care services. Design and Methods: Twenty-four case managers working in the Arizona Long Term Care System (ALTCS) were randomized into treatment and control groups. Members of the treatment group were given patient assessments for 25 ALTCS clients, estimates of the patients' risks for various adverse outcomes, and estimates of the aggregate potential benefit for each patient. Members of the control group were given only patient assessments (as is usual practice) for the same sample of 25 clients. Both groups were asked to independently write nonbinding care plans for each patient. The cost of each case manager's care plans was computed by multiplying standard costs per service times the mix and volume of services prescribed for each patient. Results: Treatment group care plan costs were, on average, lower than control group costs and closely tracked variation in estimated patient risks. Comparison group care plan costs were unrelated to risks. Implications: Information about risk and potential benefit can improve targeting of services to long-term-care clients. A prospective study using such an approach is warranted to see if provision of risk and potential benefit information would produce better clinical and economic outcomes.
